NORMRND Random matrices from normal distribution. R = NORMRND(MU,SIGMA) returns a matrix of random numbers chosen from the normal distribution with parameters MU and SIGMA.
The size of R is the common size of MU and SIGMA if both are matrices. If either parameter is a scalar, the size of R is the size of the other parameter. Alternatively, R = NORMRND(MU,SIGMA,M,N) returns an M by N matrix.
